This invention relates to improvements in illuminating devices, but more particularly to 'a li hting system for dance halls, theaters and oier amusement places where it is desirable to produce variegated light displa s.

One of its objects is to provide a revo vv able illuminating device of this character which has been desi ed to create a rolling or blending of the colored light rays one into lo the other, whereby a unique and variegated lighting eiiect is produced.

Another object of the invention is the r0- duction of a v arie'gated lighting device'w ich is simple, compact and inexpensive in con- 15 struction, which is reliable in operation, and which requires a minimum amount of power to operate it.

In the accompanying drawings e 1 is a side elevation of my'novel device. Figure 2 is a top plan view thereo Figure 3 is an enlarged vertical lon 'tudinal section of the device.

Simi' 'lar characters of reference indicate corresponding parts throughout the several 25 views.

This improved illuminating device has been designed or suspending it overhead to throw the variegated light rays downwardly and outwardly onto the door and around the 3o side walls of a dance hall stage or like amusement place. To this en the lamp structure has been shown suspended roma ceiling and includes a revolving, upright supporting post 11 journaled at its upper end in 35 bearings 12, 12 applied to a suitable casing 13 secured to the ceiling. This post carries a source of light, such as an electric lamp 14, and a reliector 15 for directing the light rays radially outward. By preference, the relector is supported in a substantially semicircular yoke or member 16 interplosed between the upper and lower ends of t e post to turn therewit The reiiector is adjustable circumferentially of this (yoke to vary the angle of the light rays, an for this purpose is provided with anadjusting screw engaging a longitudinal slot 18 in the yoke, as shown in Figure 3. The lamp 14 also repost and is mounted on an volves with the 50 arm 19 projecting radially therefrom.

post is preferably tubular in form andthe current-conducting wires 20 leading from the lamp socket 21 pass upwardly through the hollow post and are electrically connected to collector rings or collars 'Q2 secured to the 55 upper end of the post and insulated from each other. The electric current from the supply source is conducted to the collector rings through the medium of contact strips 23 yieldingly engaging said collector rings.

Motion is transmitted to the post 11 by an electric motor 2a or other source of power, the latter being connected by a sprocket chain 25 with a sprocket wheel 26 mounted on a' transverse shaft 27 which is also provided 6 5 with a worm 28 meshing with a worm wheel 29 secured to a longitudinal shaft 30 supported at its outer end in a bearing bracket v 31 and at its inner end in the adjoininv wall of the casing 13. The inner end o said 7o shaft is rovid a bevel gear 32 meshing wit a similar gear 33 secured to the upper end of the post 11. This train of gearing from the motor to the post is such that the lamp 14 and reflector 15 are revolved 75 at a comparatively slow speed.

Surrounding the lamp and refiector to revolve relatively thereto is a lamp body consisting of an upper truste-conical portion 34 preferably closed at its upper end b a disk so 35 containing bearings 36 through w ich the upper end o the post 11 extends, and a lower portion of conical shape composed of a plurality of substantially triangular shaped, colored glasses or lenses 3 These lenses are a5 rmly secured at their opposing upright ed es between inner and outer supporting strips 38 suitably fastened at their upper ends to the base of the frusto-conical portionl 34: and at their lower ends to a collar 39 ap 90 plied to a thrust bearing provided at the lower end of the post 11. The upper rustoconical ortion of the lamp body is preferably cylindrical in cross section and the lower olygonal in cross section, 95

er ends o the variegated lenses 37 'sposed within the marginal ed such frusto-conical portion. The resulting gaps or segmental openings between these the up being This parts are preferably sealed or. closed by hori- 1M zontally disposed plates 41, as seen in Figure 3, and are welded or otherwise fastened to the upper portion of the lam body. The

inner wall or surface of the ruste-conical portion 34 of the lampl body is preferably ighly finished or polis ed to form a reflecting surface, some of the lamp-rays being directed against this surface and then reflected therefrom through the lenses 37.

The lamp body 34, 37 is revolvable about the lamp 14 and its reflector 15 and preferably in the reverse direction and at a faster speed than that of these parts. Motion may be transmitted to the lamp body from the 15 shaft 30 by means of a friction wheel 42 appliedthereto and engaging an annular track or surface 43 applied tothe upper portion 34 of the lamp body, as shown in Figures 1 and 3.

By this construction and arrangement of parts,'when th transmitted to the lamp 14 and reflector 15 in one direction and to the lamp body 34, 37 in the opposite direction and at dilerent relative speeds. This relative rotation of the parts results in a variegated display Vof colors on the floor and walls of the hall which roll or blend into one another and produce a very unique and beautiful color effect, some of the rays being directrays from the lamp through the lenses 37 and others bein relected rays from the refiector 15 auf? the reflecting'l surface of the frusto-conical portion 34 of the lamp body.

I claim as my invention p 1. An illuminating device of the character described, comprising a revolving lamp body including a substantially conical lower portion having variegated lenses and a frustoconical upper portion constituting a redector in opposing relation to said lenses, a revolving llght reflector including a source of light arranged within said lamp body for directing the light rays successively through said lenses during the relative revo utions of the lamp body and the reflector, and means for transmitting motion to said revolvable parts.

2. An illuminating device of the character described, comprising a revolvable post, a

revolving lamp body supported on said post to turn relatively thereto and including a conical lower portion composed of variegated lenses and a frusto-conical upper portion forming an inner reliectin surface, a reflector including a source o ylight arranged within said lamp body opposite its lenses and fixed to said post to turn therewith, and means for turning the post and the lamp body in opposite directions. l

3. An illuminating device of the character described, comprising a revolvable post including a reflector support, a revolving lamp body applied to said post to turn relatively A 5 thereto and including a conical lower pore motor is started, motion is v for directing the ra s lenses, and means or transmitting motion to the postand the lamp body.
